What is New light emitting materials: Alternating copolymers with hole transport and emitting chromophores about?

A new type of novel high-efficiency light-emitting nitrogen-containing poly-(phenylene vinylene) (PPV)-related copolymers, which have hole-transfer moieties such as triphenylamine (TPA) and conjugated aromatic units such as 4,4Ј-biphenylene, 1,4-phenylene, 2,5-dimethyl-1,4-phenylene, 1,4-or 1,5-naphthylene, and 9,10-anthrylene, was designed and synthesized by the well-known Wittig-Hornor reaction. The resulting alternating copolymers were highly soluble in common organic solvents. They can spin-cast onto various substrates to give highly transparent homogeneous thin films without heat treatment. The introduction of TPA units in the PPV backbone improved processibility and limited the -conjugation length. Furthermore, the additional -electron delocalization between the lone-paired electron in the nitrogen atom and -electrons in the conjugated units contributed to the improvement of the fluorescence quantum yields of these copolymers. All these alternating copolymers except TPA-PAV have high-efficiency photoluminescence and they are very promising for light-emitting diodes (LEDs). It is very promising that TPA-PAV will emit white light when used in LED device due to the broad emissio
